System and Method for Detecting and Notifying Access to Dangerous Areas in Workplace Using Image Processing and Location Tracking Technology

1. A dangerous area notification system comprising: a server configured to partition a workplace into grating sections to assign coordinates, set a dangerous object or a dangerous area, and broadcast a notification message including coordinates of the dangerous object and information on the dangerous area; and smart glasses configured to recognize an augmented reality marker installed in the workplace to display a same grating as a grating generated by the server in an augmented reality mode, continuously identify coordinates of the smart glasses, identify the coordinates of the dangerous object or the information on the dangerous area included in the notification message received from the server, and display a grating of the dangerous area or the dangerous object in the augmented reality mode when the coordinates of the smart glasses are adjacent to the dangerous object or the dangerous area using the coordinates of the dangerous object or the information on the dangerous area, wherein the augmented reality marker is located at each vertex of a grating partitioned by the server on a floor of the workplace, and includes direction information in which the grating is to be generated.

2. The dangerous area notification system of claim 1 , further comprising: a camera configured to provide an image obtained by photographing the workplace to the server, wherein the server is configured to detect a movement of the dangerous object through image analysis of the image obtained by photographing the workplace, identify the coordinates of the dangerous object and information on the dangerous object changed in response to the movement of the dangerous object, and generate and broadcast the notification message including the coordinates of the dangerous object and the information on the dangerous object that are identified.

3. The dangerous area notification system of claim 1 , further comprising: at least three signal generators configured to output a signal for identifying the coordinates of the smart glasses, wherein the smart glasses are configured to continuously identify the coordinates of the smart glasses by performing triangulation using signals outputted from the at least three signal generators.

4. The dangerous area notification system of claim 1 , wherein, when displaying the grating of the dangerous area or the dangerous object in the augmented reality mode, the smart glasses is configured to set an additional grating zone surrounding the dangerous area as a warning area, and display the warning area in the augmented reality mode in a different color from that of the dangerous area.

5. The dangerous area notification system of claim 4 , wherein, when displaying the grating of the dangerous area or the dangerous object in the augmented reality mode, the smart glasses are configured to display an area with the dangerous object or the dangerous area in red, and display the warning area in yellow.

6. The dangerous area notification system of claim 1 , wherein, when displaying the grating of the dangerous area or the dangerous object in the augmented reality mode, the smart glasses are configured to display the information on the dangerous area or the dangerous object present in a blind spot with a letter or a symbol on the smart glasses when the dangerous area or the dangerous object is not in a field of view of the smart glasses.

7. A method for notifying a danger by a dangerous area notification system comprising: partitioning, by a server, a workplace into grating sections to assign coordinates; setting, by the server, a dangerous object or a dangerous area; broadcasting, by the server, a notification message including coordinates of the dangerous object and information on the dangerous area; recognizing, by smart glasses, an augmented reality marker installed in the workplace and displaying, by the server, a same grating as a grating generated by the server in an augmented reality mode; continuously identifying, by the smart glasses, coordinates of the smart glasses; identifying, by the smart glasses, the coordinates of the dangerous object or the information on the dangerous area included in the notification message received from the server; and displaying a grating of the dangerous area or the dangerous object in the augmented reality mode when the coordinates of the smart glasses are adjacent to the dangerous object or the dangerous area using the coordinates of the dangerous object or the information on the dangerous area, wherein the augmented reality marker is located at each vertex of a grating partitioned by the server on a floor of the workplace, and includes direction information in which the grating is to be generated.

8. The method of claim 7 , wherein the broadcasting, by the server, of the notification message including the coordinates of the dangerous object and the information on the dangerous area comprises: detecting a movement of the dangerous object through image analysis of an image obtained by photographing the workplace; identifying the coordinates of the dangerous object and information on the dangerous object changed in response to the movement of the dangerous object; and generating and broadcasting the notification message including the coordinates of the dangerous object and the information on the dangerous object that are identified.

9. The method of claim 7 , wherein the continuously identifying of the coordinates of the smart glasses comprises: continuously identifying the coordinates of the smart glasses by performing triangulation using signals outputted from at least three signal generators.

10. The method of claim 7 , wherein the displaying of the grating of the dangerous area or the dangerous object in the augmented reality mode comprises: setting an additional grating zone surrounding the dangerous area as a warning area, and displaying the warning area in the augmented reality mode in a different color from that of the dangerous area.

11. The method of claim 10 , wherein the displaying of the grating of the dangerous area or the dangerous object in the augmented reality mode comprises: displaying an area with the dangerous object or the dangerous area in red, and displaying the warning area in yellow.

12. The method of claim 7 , wherein the displaying of the grating of the dangerous area or the dangerous object in the augmented reality mode comprises: displaying the information on the dangerous area or the dangerous object present in a blind spot with a letter or a symbol on the smart glasses when the dangerous area or the dangerous object is not in a field of view of the smart glasses.
